All copper traces have their own internal resistance that opposes the flow of current, raising the temperature of the track in the process.
The designer must reduce the resistance of the track to the extent that the increase in temperature remains within limits.
Current passing through the track causes it to heat up, and it loses heat through convection to the surrounding air, thereby stabilizing the temperature. However, this is true only for the traces present on the outermost layers of a multi-layered board.
For traces in the inner layers, heat removal is only through the PCB material, which is less effective than air. Designers must compensate for this difference when designating traces carrying high currents in inner layers. The alternative is to assign high current traces to only the outermost layers.
